Application filed May 20,

To all whom t may concern: t

Be it known that I, HERAULT A. TRESTER, citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Road Forms, of which the following isa specifi-V cation. Y

The present invention relates to a metal form which is designed for use when constructing roads, pavements or curbing from concrete or other plastic material, and has for its object to provide a device of this charf 'acter which can be quickly and accurately assembled in operative position and which will provide an eective form for shaping the concrete or plastic material in the desired manner.

Further objects of the invention are to provide a form of this character which can be used repeatedly and will be much rmore economical `than wooden forms which must be set up and knocked vdown for eachuse thereof and rapidly deteriorate, and which can be set up with accuracy and used effectively by unskilled labor.

With these and other objects in view, the invention consists in certain combinations, arrangements and associations of the parts, as will more fully appear as the description proceeds,- the novel features thereof being pointed out in the appended claims.

For a full understanding of the invention reference is to be had to the following description and accompanying drawings, in which z-f Figure 1 is a rear elevation of affragmentary .portion of a road form which is constructed inl accordance with the invention, one of the stakes andsupporting hangers being shown. v

Figure 2 is a transverse through the road form. y

Figure 3 is a top plan view of theconstruction shown by Figure 1.1 j

all of the views ofthe drawing by like reference characters.- f y Referring to the drawings, which illustrate one possible embodiment of the invention, the numeral 1 designates a stake `which has the lower endvthereof pointed so that I it can be readily driven into the ground. The stake is preferably formed of metal and is shown as having a circular cross section. The driving head 2 is applied to the stake and this drivingA head serves the double function ofprotecting the head of the stakeA when it is driven in position andalso ofproviding a means of attachment forv the The hangerB has a vertically elongated working head which supports and fits against the rail 1, and is also formed with a rearwardly 4extending arm 3a which fits against the flat face 2a of the drivinghe'ad 2.` The arm 3a is provided with a horizontally disposed rib 5 which is received within a correspondingchannel in the flat face 2a of the driving head. Somesuitable fastening means such as a Uvbolt 6 is provided for securing the hanger arm 3a to the stake head, and the two arms ofk this U bolt extend through horizontal slots 7 in the hanger. Nuts 8 are fitted upon t-he U bolt, andit will be` obvious that when these nuts are tightened the hanger will` be held rigidly inan adjusted position, although when the nuts are loosened the hanger can be adjusted hori- Zontally upon the stakewithinthe limits defined by the `possible play of the armsof the U bolt 6 within the slots 7. f

The rail is formed ina number of similar and interchangeabley sections 4 which can be assembled to providefa continuous 4rail `of any desired length, said rail being* supportedlbyjalplurality of the stakes 1 whichl arerprovided at Lnecessary and proper Vintervals of space. `The rail sections 4 have .j what may be termed a channel formation,

ther working faces 1-1V thereof 'being substantiallysmooth `and-flat, andthe longitudinal edges of the rail sections beingprovidedk with returned flangesi?. yOpposite ends ofv eachy railsection are provided'with coupling tongues 9 which .area'rrangedvfatopposite rsides, of the section so that when assembling va numbe'rofrail sections-the ra'll sections are reversible and,4 it is immaterial. which "ends thereof are'. broughtinto an abuttin relation-, The coupling tongues `9.l projecting from the ends of4 the rail sections atopposite sides thereof, may be formed of sheet metal pieces which arecurved to conform to the shape of the; anges 4b of the rail sections, and which' are' secured to` the rail sections by suitable fastening means V such as the rivets 10. When two of the rail sections are assembled inan end to end relation the two coupling tongues 9 which arek brought intoi operation'- are arranged atopposite edges of the rail andi-each interlock with.thereturned flange 4? ofthe otherv rail. TheV rail sections are. thus held rigidly in alinement withtea'chgl other without the necessity of; utilizing any boltstor other removablefastening elements; The rail sections can bek readily forced together orV pulled apart,V and. there is no possibilityof the sections being incorrectly assembled', since the'sections a're all similarivand interchangei able, and thereiare no rights and lefts'. The

tended; bearing plate or pedestal i2 which may project outwardly under the lower edge of the rail. rlhisbe'aringplate 12 may alsoserve to vengage the top of the ground t'o'suppo'rt the stakeat the proper elevatifo'n and prevent it from sinking after it hasqonee Ybeen properly positioned: A suit- 'ablel lockiofr clamp such as the cam 13 is provided for holding the sleevel 11 in an adjusted; position, said' Y@am being' provided withfan` operating lever'` 14' and being'vpreferably-arrangedin such a- IfnannerV that an upward movement of the locking member will-'serve tothrow the canili'nto operative position; Apossible'- contact of the lever withl the surface of the ground or with someobstruction will thusserve to forceV the cani more firmly intoy locking position instead-of to release the same', as will also any 'downward'V-pressure on `the stake.

- In; using the form a number ofthe stakes 1 willi` lie-driven' into' the ground at suitable"l intervals along .the line which is to beo'c'cupie'd by the form. These stakes carry the 'hangers Supon which the assem- AYbled rail'sefctions t can be" placed. These rail" sections can then be brought into accurateI alin'einent by adjusting* the hangers ill-horizontally .upon4 thestake's and compen- 4sationthusquicklymade for anyv lack of Aali heiniieiit in the stakes- 6. The basev plates lf2-:ofi the sleeves. l'lfn'ay be 1 adjusted to support the'lower edges of the rail, and may rest upon the surface of the ground so as to prevent sinking of the stakes.

The channel rails are so shaped that when using a camping machine or any other device which rides upon the rails, any stone, concrete or the like resting upon the flanges will be dislodged and removed by the wheels tion, as well as a saving, should yone edge of a rail be damaged orv rendered inoperative for any reason.

While I have illustrated and described one possible embodiment of the invention I do not wish to be restricted to the exact details of construction which have been shown, since it will be obvious that numerous modifications and changes canV be made therein without departing in any manner from the spirit of the invention. Y
